<b>Redmi 4 — low-maintenance metal flagship phone</b>
Xiaomi Redmi smarphones are a burgeoning phenomenon! Redmi 4 Standard Edition (SE) and Redmi 4 High Edition (HE) finally saw the light with a bunch of fascinating features: they both received a solid metal casing, are equipped with a fierce Snapdragon processor, have a fast MIUI 8 operating system with a “second space” option, enabling to double open applications.
<b>Metal body shines at every angle</b>
This is a metal era for Xiaomi’s handsets. The metal used for the body not only provides its endurance in terms of structure and color but also protects internal parts and disperses heat well.
Redmi 4 SE and Redmi 4 HE has an iconic metal capsule. It takes 30 steps to go from a solid aluminum ingot to the finished product, including CNC cutting, anodizing, sandblasting processes and polishing. Such an approach ensures a superior grip experience from the first moment you take it.
<b>Advanced energy management</b>
Redmi 4 HE houses as large as a 4100 mAh battery. Combined with a low-power Snapdragon 625 processor, based on 14-nm technology, it translates into 9 days of performance with moderate usage. MIUI 8 helps to maximize charge efficiency, preventing background applications to start automatically. Sudden battery depletion is not to worry about so you can take a rest watching 10 episodes of your favorite TV show.
<b>High-performance Snapdragon processor</b>
Redmi 4 hosts a great performance processor in the same vein as a previous generation of Redmi phones. Application opening became a matter of milliseconds. Redmi 4 HE sports a thunderous 8-core Snapdragon 625 chip with 64-bit architecture. Redmi 4 SE is packed with a lighter Snapdragon 430, which is still efficient to handle everyday applications. For those, who like to play HD games, watch videos, use the phone for continuous Internet connection, this one is a great solution.
<b>Easy-to-use MIUI 8 dual-device mode</b>
You must have noticed that it is possible to create several accounts on your laptop or PC with different apps, themes, and overall settings. Would you want to have such a feature on your smartphone? Xiaomi has improved its operation system enabling device owner to create a “second space”.
<b>13 MP camera with fast autofocus to capture fleeting moments</b>
Most beautiful moments of our lives are short-lived. To be able to grasp and re-experience them with joy an ultrasonic camera is required. Redmi 4 camera is equipped with a fast focusing technology that allows shooting photos within milliseconds. Capture fireworks show or a cute cat sticking out his tongue.
